CONVEYING MACHINERY.

sPEcIMcA'I'IoN forming part of Letters Patent No. 523,083, dated July 17, 1 894.

Application filed sweater 20,1893. Serial No.491,502. (Nomodeld To all whom it may concern:-

Be it known that we, DA'NIEL O. SAEMAN and THOMAS W. SAEMAN, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Conveying Machinery; and we do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains-to make and use the same.

Our present invention relates to conveying sirable place of deposit or storage.

The invention will be fully disclosed in the following specification and claims In the accompanying drawings which form part of this specification Figure lrepresentsa side elevation; Fig. 2 a front end elevation with the elevator chain and buckets removed; Fig. 3 an enlarged end view partly in section of the upper end of the elevator frame; Fig.

4. an enlarged side view of the upper end of the elevator frame, the inclined and horizon- .tal conveyors; Fig. 5 a section on line, was on Fig. 4; Fig. 6 a section on line 11 y, on Fig. 4

' showing the several sprocket wheels in elevation; Fig. 7 a top plan view of the-entire mechanism with the elevator-chain and buckets removed; vFig. 8 an enlarged sectional detail showing the horizontal conveyor, the upper rails of the movable frame and their supports and the sprocket wheels at. the inner end of the boom; Fig. 9 an inner end -viewof the lower end of the elevator frame; Fig. 10 a vertical longitudinal section of the boot at the lower end of the conveyor frame, and Fig. 11 a transverse section of the same.

Reference being bad to the drawings and the letters thereon A indicates the main stationary frame, B a longitudinally movable frame supported upon suitable rollers 01. and is designed to be moved out and in with reference to the main frame to place the elevator-frame 0 and the elevator D in proper position for unloading vessels ofdiderent widths.

. The frame 13 may be moved out by acable the main shaft (1 which maybe connected with an engine or any 1 suitable source of power, and be moved in by a cable or rope e engaging the front end of the frame at one end and a Windlass E at the other end, or it may be moved by any suitable means which will be readily suggested by the skilled mechanic.

The sides f of the elevator-frame are slotted at g and engage transverse pins h in the frame B by which the two are secured together,and at the upper end of the elevator-frame it is connected to the boom E by the shaft 2' which supports the sprocket-wheels-k upon which the elevator-chain l is supported, and said elevator is provided with buckets m of the usual form.

The elevator-frame and the elevator-chain descend automatically by gravity as the material isremoved from the vessel tokeep the lower end of the frame and the buckets of the elevator in contact with the material to be removed.

The sides n n of the boom E at their front ends engage the shaft iwith a th'imble or sleeve 0 interposed to avoid wear, see Fig. 3, and at their rear ends they engage the shaft 10 which passes through the sector shaped slots qq in the brackets F supported on the upper timber of the stationary frame A, and on the outside of each of the sides 12. 'n are metal rods r r whichalso engage the shaftsz' and .p and stifien the boom. 1

The brackets F may be bolted to the sides of the upper timber of theframe or they may be provided with a right angled flange and be bolted to the upper edge of said timber.

. As the elevator-frame C and the front end of the boom E rise and fall, the rear end of the boom swings vertically upon the shaftp, and as the frame B is moved out or in with relation to the fixed frame A, the rear end of the boom travels back and forward in the slots q q in the. brackets -F and thereby keep the driving belt G taut between the pulley s on the main shaft and the pulley t onthe shaft 19. I p

H indicates a horizontal and fixed or stationary conveyer which rests upon the frame ,A, and I an inclined and movable conveyer the sides u 'u, of which at their front and upper end are pivotally connected to the shaft 4; which supports the pulley w, and the rear end of said conveyer is supported upon the on the upper edge of the sidesof the station-- stationary 'conveyer II by wheels a. a, (see Figs. i and 5) which travel back and forward ary conveyor as the elevator-frame and the front end of the boom rise and. fall.

' The conveyer I is provided with an endless belt or apron b on which are arms or blades c to draw the material down toward and into the stationary conveyor H, which is provided with a like constructed belt or apron d. having arms or blades e which draw the material to the rear end of the conveyer from ..which it may fall upon the ground or it may be conducted toany desired placeof deposit. I The belt f transmits motion to the elevatorchain Z by engaging the pulley g on the shaft 't', and the chain Zengaging the sprocket wheel '71 on the shaft'vtransmits motion to the belt or apron I) through belt 12 and pulleys 22 and b and the belt 70' which engages ,the

the sides at at when the boot is required, and

as readily removed when its use is no longer necessary. The sides 41' may be detachably secured to the sides f of the elevator-frame by any suitable means.

When the bottom of the vessel has been reached and all the material removed from one compartment or within easy reach of the elevator, the frame and the elevator-chain Z are raised out of the hatch of the vessel by means ofany suitable hoisting mechanism such as themain shaft (1 or bythe windlass E to which a cable or rope (not shown) may be attached and secured to the lower end of the frame, for which purpose we'have provided a-chain o" for the cable or rope to engage. This hoisting rope being of well known construction has been omitted from the drawings to avoid confusion.

supporting frame, a longitudinally movable and self adjusting-frame pivotally and slidably attached at its inner end to said supporting-frame, and an elevator-frame pivotally attached at its upper end to the outer end of said self adjusting-frame; in combination with drive mechanism supported by said self adjusting-frame and suitable elevating mechanism.

2.
